The question whether technological progress displaces employment or whether technological advance is beneficial for the level of employment has been in the core of economic dispute for over two centuries. The beneficial might be achieved by several compensation mechanisms within the economic system. In this paper we categorize these compensation mechanisms into two basic categories that reflect...

ISO 9001 (ISO 1987) certification issues are bringing-out calibration anxieties. The rush to document calibration intervals for certification purposes is often driving-up costs. Both instrument manufactures and calibration services are benefiting financially from calibration anxiety brought on by “ISO systems requiring you to say what you do and do what you say to meet the ISO specifications”. ...

The traditional approach to random vibration testing using fast-Fourier-transform simulation has become out-of-date, since it is restricted to consideration of the power spectral density only. The latter means that the FFT approach is based on a Gaussian random signal model. However, the MIL-STD810F standard establishes that “care must be taken to examine field-measured probability density for ...

In a testing environment, where an IUT communicates with multiple entities, a tester may have di ering degrees of controllability on the interactions between these entities and the IUT: directly controllable, semicontrollable, or uncontrollable. In this paper, a graph conversion algorithm is introduced that o ers the testability of both the directly and semicontrollable inputs, while avoiding r...

Time and frequency characterization of precision clocks and oscillators is an important task in the maintenance of time and frequency standards. Recently, time domain signal characterization of clocks is generally preferred and several pedormance measures of clocks and oscillators are defined in ITU-T Recommendation G.810. Among these measures, Maximum Time Interval Error (MTIE), Time Deviation...

BACKGROUND High-fluence diode lasers with contact cooling have emerged as the gold standard to remove unwanted hair. Lowering the energy should result in less pain and could theoretically affect the efficacy of the therapy. OBJECTIVE To compare the safety and efficacy of a low fluence high repetition rate 810-nm diode laser to those of a high fluence, low repetition rate diode laser for perma...

OBJECTIVE To investigate the clinical effects of laser acupuncture therapy for temporomandibular disorders (TMD) after ineffective previous treatments. METHODS A retrospective observational study was conducted in 29 treatment-resistant TMD patients (25 women, 4 men; age range, 17-67 years). Subjects were treated 3 times per week for 4 weeks with the Handylaser Trion (GaAlAs laser diode, 810 n...

Ball-milled alcohol-insoluble residue (AIR) was prepared from switchgrass (Panicum virgatum var Alamo) and sequentially extracted with 50 mM ammonium oxalate buffer, 50 mM sodium carbonate, 1 M KOH containing 1% NaBH(4), and 4 M KOH containing 1% NaBH(4). Arabinoxylan was the most abundant component of the 1 M KOH-extracted fraction, which was treated with endoxylanase to generate oligosacchari...
